BUSHING FOR BUNGS.

SPECIFICATION forming part of Letters Patent No. 233,638, dated October 26, 1880.

Application filed September 18, 1880.

T 0 all whom it may concern Be it known that I, WILLIAM G. PENNY- PAOKER, of \Vilmington, in the county of New Castle and State of Delaware, have invented certain new and useful Improvements in Bushing for Bungs; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to letters of reference marked thereon, which form a part otlthis specification.

Figure 1 is a top view 'of the head of a cask or vessel having my improved bun g-bushing applied. Fig. 2 is asection on line 00 0c of Fig. 1. Fig. 3 is a view of the under side of the head, showing the mode of attaching the bushing to the cask or vessel.

The same letter indicates the same part wherever it occurs in the drawings.

My invention relates to the bushing ot the bungs of vessels intended to contain oil or other liquids which, from their nature, are apt to escape between the bung and the side of the bung-hole.

It consists in inserting in the bung-hole, before the introduction of the bung, a cylindrical bushing made of the paper or material known as vulcanized fiber, holding it in position and keeping it from turning by means of pegs, and screwing a metallic threaded bung into said bushing, all as hereinafter more fully set forth.

In the drawings, H marks the head of the cask or vessel. In the bung-hole I insert a (Model) cylinder, A, formed of a kind of paper specially prepared to resist the passage of oil, and known in commerce as vulcanized fiber. The cylinder is driven in tightly, and held in place and kept from turning by means of cylindrical pegs P P, driven into holes so bored at the sides of the bung-hole as to allow the side of each peg to be forced into the edge of the bushing, as shown in Figs. 2 and 3. Into this bushing the metallic bung B is screwed, its thread cutting its way into the sides ot'the bushing and securely closing the bung-hole.

I have found by experiment that bushing of this kind, applied as described, will perfectly confine oil and other materials of a like nature which are liable to escape when held by a screw-bun g of the ordinary character.

What I. claim is l. A bushing for oil and other casks and vessels, consisting of a cylinder made otvulcanized fiber, fixed in the bung-hole by pins. as described, and receiving, and by its elasticity holding, the threads of ascrew-bung, all as set forth.

2. The combination, with the head or side of a vessel provided with a bung-hole, of the bushing A, screw-bung B, and pegs P P, in the manner and for the purpose specified.

In testimony that I claim the foregoing as my own invention I afiix my signature in presence of two witnesses.
